President Trump's travel ban on the citizens of seven Muslim-majority countries has created confusion and concern across the Middle East and parts of Asia.
The Organization of Islamic Cooperation, which represents dozens of Muslim countries, expressed "grave concern," warning that it would "embolden the radical narratives of extremists." The Arab League slammed it as unjustified.
Only one of the countries on Trump's list -- Iraq -- has a significant trading relationship with America. It is the sixth biggest source of U.S. oil imports.
But the ban could damage wider U.S. interests. There are around 47 countries and territories in the world where Islam is the dominant religion. Total U.S. trade in goods with those countries topped $220 billion in 2015, according to the U.S. Census Bureau. In the first 11 months of 2016, the value of trade reached $194 billion.
Put another way, the U.S. does roughly 6% of its total trade with Muslim-majority countries.
The bulk of the trade in goods -- 94% -- was with just 15 countries, including Malaysia, Saudi Arabia, the United Arab Emirates, Turkey, Indonesia and Iraq.
Here are the U.S.' top trading partners in the Muslim world.
